Shallot is an essential vegetable commodity in Indonesia. In north of Sumatera, shallot yield has decreased each year. Low production of shallot Indonesia one of them due to the application of cultivation technology. One way to increase the production of shallot is the improvement of cultivation techniques and organic fertilizer.The objective of the research was to determine the response of the growth and production of shallot on the application of municipal waste compost and K fertilizer. Research conducted at the Research Field of Faculty of Agriculture, University of Sumatera Utara, Medan on June to August 2015, using a randomized block design factorial with two factors: Municipal Solid Waste Compost (0, 7.5, 15, 22.5 t / ha) and K fertilizers (0, 75, 150 KCl / ha). Variables observed was the length of the plant , number of leaves and diameter of bulbs dry. The results showed that the urban waste compost not significantly effect on all variables observation, whereas the K fertilizer significantly effect of 3-5 MST plant length and diameter of bulbs dry. Interaction between urban waste compost 7,5 ton/ha and K fertilizer 75 kg KCl/ha is the best treatment to increase the growth and production of shallot.
